Salt Pepper Finish Polished Concrete Floor Cardiff

This polished concrete floor was on the whole quite well laid but unfortunately there was some confusion between the installer and the builder where the installer insisted on applying a cure and seal product, which as you can see had a large amount of curing marks in the surface after the builder covered the floor with protective sheeting.

“Great service from CARRcrete via phone. Unfortunately our concrete hadn’t been laid exactly to specification, so there were a few hiccups! Also, there were too many miles between us for CARRcrete guys to pop round and review the situation!! But the floor was polished to a high standard, and we love it! – Sue Bickerton”

The Concrete Polishing Process

This floor was originally specified to be a cream finish where we simply polish the laitence on the surface and remove hardly any material. But due to the application of said cure and seal, this finish had to be changed to a salt and pepper look due to the removal of the sealer and affected surface.

If the concrete slab installer had not applied the thick coating of resinous cure and seal we would have honed and polished the surface using our fibre backed diamond abrasive pads, which work in a very gentle way to smooth out and polish the surface without removing excess material, thus preventing any sand and aggregates from showing through. This process we have found to keep the cloudy industrial appearance that everyone loves about our InfinityFloor Cream finish.

“The way the slab was cured caused many colour variations“

Dave Carr’s thoughts on this Polished Concrete Floor Cardiff Wales project
I found this floor both frustrating and challenging due to the problems we inherited from the installation process whilst still trying to maintain some semblance of the chosen InfinityFloor specification. The floor had every chance of being a perfect InfinityFloor Cream finish but on closer inspection the cure and seal product was used like a pore filler to hide minor defects within the surface. The way the slab was cured caused many colour variations that could not be removed without significantly changing the appearance of the floor. After all the techniques used I think this floor came out looking superb considering the challenges it posed, the colour was lovely and rich with a nice classy level of shine across the surface.


The processed used on this concrete flooring

  1. Honing of the concrete surface with our CARRcrete hybrid transitional diamonds to remove the cure and seal
  2. Filling of micro pores within the concrete surface with CARRcrete PROgrout
  3. Densification of the honed surface with CARRcrete PROhard Extreme silicate densifier
  4. Polishing of the hardened surface with our CARRcrete planetary diamond polishing pads
  5. Application and burnishing of our guard sealer CARRcrete PROguard
